Patent GB-617488-A (GB)
Title: Manufacture of resinous condensation products
IPC: C08G69/26
Filed: 1946-10-03
Abstract: Resinous condensation products are produced by heating humic acid, or an ester or acid halide thereof with a polyhydric alcohol, an aliphatic polyamine or an amino alcohol.  Humic acid is the dark coloured, organic, alkali-soluble material obtained from coal, liguite, peat or decomposed vegetable matter.  The material used in the examples was obtained by the oxidation of coal with nitric acid. Suitable polyhydric alcohols are glycerol, ethylene glycol, diethylene or trimethylene glycol.  Suitable polyamines are ethylene diamine, trimethylene diamine, tetramethylene diamine and hexamethylene diamine.  Suitable amino-alcohols are mono- and di-ethanolamine.  Condensing agents, e.g. sulphuric acid, hydrochloric, p-toluene sulphonic or a -camphor-10-sulphonic acid may be presented.  Preferably less than one equivalent of humic acid is used for equivalent of the other ingredient, the excess ingredient being removed during and/or after reaction.  The initial temperature is preferably low.  It is slowly increased to about 200 DEG  C.  The final stage may be under reduced pressure.  The mixture may be stirred or a current of nitrogen may be passed through it.  Oxygen is preferably excluded.  The final stage of the condensation may be performed in a mould.  The condensation may be stopped, while the product is still thermosetting.  Plasticisers, e.g. dibutyl phthalate, tricresyl phosphate or stearic acid, or fillers, e.g. wood flour, asbestos powder or pitch coke may be mixed with the thermosetting products, or they may be modified by heating with oils, monoboric or other organic acids, or monohydrics or polyhydric alcohols.  The products may be moulded, dispersed in organic liquids for coating compositions or powdered for use as a carbon black substitute.  Examples describe the preparation of resins from humic acid and ethylene glycol; humic acid and glycerol; methyl humate and ethylene glycol; humic acid and ethylene diamine; humic acid and monoethanolamine; humic acid and monoethanalamine; humic acid and hexamethylene diamine.  The last two examples describe the moulding in an atmosphere of nitrogen of products from humic acid and ethylene glycol and diethylene glycol respectively.

Title: Improvements in or relating to apparatus for registering the work output of internal combustion engines
IPC: G01L3/24
Filed: 1936-10-30
Abstract: 468,663. Internal-combustion engine indicators. UHER, E. Oct. 30, 1936, No. 29588. Convention date, Nov. 4, 1935. [Class 106 (ii)] In a device for measuring the work output of an internal-combustion engine the pressure in the engine induction pipe is used to adjust the variable transmission drive of the revolutioncounting mechanism. The engine shaft 23 oscillates through linkage, including a slide block 29 on a rocking lever 27, an arm 21 of a known counting mechanism. By means of the pressure-responsive diaphragm device 6 subjected to the pressure in the induction pipe 4, a lever 13 pivoted at 11 is moved so as to vary the height of the point 17 and consequently the position of the slide block 29 and the stroke of the arm 21. A pointer 30 operated by the other arm of lever 13 indicates on a scale 31 the pressure in the induction pipe. The scale 31 is slidable with respect to a fixed scale 32 which indicates the barometric height. In order to make the height of the pivot 17 and therefore the drive of the registering mechanism responsive to changes of temperature, the lever 13 is formed in part as a bimetallic bar, the upper bar 15 having a greater coefficient of expansion than the lower bar 16.

Abstract: 364,569. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., HASSELT, M. V., LATIMER, K. E., and LONG, A. L. ; Columbia House, Aldwych, London. Oct. 3, 1930, No. 29641. [Class 40 (v).] In a submarine cable signalling system in which voice frequency signals and carrier frequency signals are transmitted in both directions over a two-wire line and separated into individual channels at the terminals, a common hybrid coil or the like is used to associate voice frequency and carrier frequency channels with the line. In the known arrangement shown in Fig. 3, the channels are separated by high and low pass filters HPF, LPF before passing to the hybrid coils HC, HV for coupling to the carrier and voice transmitting and receiving circuits CRC, CTC, VRC, VTC. In balancing the line TWL at carrier and voice frequencies by the networks BNC, BNV the effects of the filters HPF, LPF and line repeating coils LR have to be included which leads to difficulties in manufacture. According to the invention, these and other difficulties are obviated by the system of Fig. 4, in which the hybrid coil H is common to both channels which are separated by filters unassociated with the line TWL which may thus be balanced by a single network BN. The line repeating coil is eliminated by using a hybrid coil of the type shown in Fig. 2. The invention is particularly applicable to submarine cable systems, the hybrid coil H being located in a hut on the beach and the portions LL extended to the repeater station as land lines.
